The purpose of the present study was to compare and quantify with ultrasound imaging (USI) the extensor digitorum longus (EDL), tibialis anterior (TA) and peroneus muscles (PER) muscle thickness and cross-sectional area (CSA) between chronic non-insertional Achilles tendinopathy (AT) and healthy subjects.
a sample of 143 individuals was recruited and divided in two groups: chronic non-insertional AT group (n = 71) and a healthy group (n = 72). The thickness and CSA were assessment by USI for EDL, TA and PER muscles in both groups.
The thickness evaluation for the TA muscle increased showing statistically significant differences (P = 0.018) as well as for the thickness of the PER muscles significant differences (P = 0.001) were observed in favor the tendinopathy group. The CSA measurements showed statistically significant differences for a decrease in EDL (P = 0.000), TA (P = 0.001) and PER muscles (P = 0.011) for the tendinopathy group with respect to the control group.
The CSA of the EDL, TA and PER muscles is reduced in participants with chronic non-insertional AT. The thickness for TA muscle is increased as well as a decrease of PER muscles thickness is presented for the AT group with respect to the control group.
本研究旨在通过超声成像（USI）比较和定量评估慢性非附着性跟腱病（AT）与健康受试者的伸肌趾长肌（EDL）、胫骨前肌（TA）和腓肠肌（PER）的肌肉厚度和横截面积（CSA）。
招募了 143 名个体，并将其分为两组：慢性非附着性 AT 组（n=71）和健康组（n=72）。使用 USI 评估两组的 EDL、TA 和 PER 肌肉的厚度和 CSA。
TA 肌肉的厚度评估显示出统计学上的显著差异（P=0.018），PER 肌肉的厚度也有显著差异（P=0.001），均有利于 tendinopathy 组。CSA 测量显示 EDL（P=0.000）、TA（P=0.001）和 PER 肌肉（P=0.011）的减少在 tendinopathy 组与对照组之间存在统计学显著差异。
患有慢性非附着性 AT 的参与者的 EDL、TA 和 PER 肌肉 CSA 减少。TA 肌肉的厚度增加，而 AT 组的 PER 肌肉厚度减少。
